Intervention model
Wed, Apr 14, 2027 · Week 13 · Biotechnology for Health (Biomedical Innovations)
Today's goal: Model how a public health control measure changes the course of an outbreak.
What a finished product looks like
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Chosen intervention: isolation of symptomatic cases for the gastrointestinal outbreak.
Target population: people who are already symptomatic, because they are the ones currently shedding the pathogen.
Prediction: Isolating cases removes infectious people from contact, so new-case incidence should level off and then fall over the next week instead of climbing.
Before-and-after curve: before isolation, the curve rises steeply; after isolation, the curve flattens and bends downward.
Limitation: Isolation only works on people who KNOW they are sick. If the pathogen spreads before symptoms appear (presymptomatic spread), isolation will miss those transmissions, so it cannot stop the outbreak alone.
Also due today: Submit your intervention model in the course LMS today.
